There are other too like Apple Safari for Windows, Avant Browser, Comodo Dragon, Crazy Browser, Dooble Web Browser. Lunascape, Maxthon 3, Netscape Navigator that started it all but has now gone under, Ocra Browser and many more but even their combined share of the Browser Market is negligible.
In reality however the choice is only between Chrome, Firefox. IE and Opera. And Opera apart from being very fast, has certain features that the other three don't have. The best is its ability to start a broken download again from where it broke off.
